My favorite science experience was when we looked at the chemical results from our field experiments. We saw that our experiment had worked and that our hypotheses (hi poth uh ses) about the effects of winter climate change were correct. A hypothesis is an unproven idea. With a complicated field experiment, so many things have to be done exactly right to get scientific results. Itís great fun when it all happens the way it is supposed to!
